Abstract

A model of a superradiant laser comprising of N three-level systems driven by two pumping lasers is considered in semiclassical approximation. Steady-state equations for density matrix elements are solved both analytically and numerically. Various properties of generated light are investigated. It is found that such a laser can exhibit both superradiance, when the intensity scales as N2, and subradiance when the intensity does not depend on N. The phase of the laser field is locked to the relative phase of the pumping lasers.
